Abstract

PURPOSE:To dispense with a specific dedicated switch to detect the maximum quantity of paper money by detecting the accumulation of the maximum quantity of paper money in an accumulation place by the increment of a load on the motor of a reciprocal moving means. CONSTITUTION:A timer T starts when starting the stroke of the reciprocal moving means consisting of a presser plate 7, the motor M2, and a cam 8, etc., and timer operating time length corresponding to a time quantity ordinarily required for the motor M2 to drive the reciprocal moving means via one reciprocal stroke of the reciprocal moving means is clocked. The operation of a carrier switch S3 is completed while the timer T is operated when no heavy load is applied, however,the operation of the switch S3 is not completed while the timer T is operated when the heavy load is applied. A control means recognizes an overload by confirming the fact that the operation of the switch S3 is not completed within the operating time of the timer T, and detecting the fact that the reciprocal moving means does not pass by prescribed stroke distance within prescribed time, then, detects the maximum quantity of paper money.

It is something.

[For production]

The stacking operation of five banknotes in the stacking means is performed as follows.

starting rotation of the motor of the reciprocating means, applying drive current to the motor by the carrier switch means until the motor rotates enough to complete driving of the reciprocating means for one reciprocating stroke; Accordingly, the reciprocating means makes one reciprocating stroke over a predetermined stroke distance. This single reciprocating stroke pushes the banknotes on the conveyance path in a direction perpendicular to the plane of the banknotes through the opening and into the stacking area, onto the flat banknote bundle already stacked on the banknote compression plate. As a result, upon return of the reciprocating motion over the predetermined stroke distance, the bill compression plate neatly compresses and holds the additional bill and the stacked bundle against the channel member. In this way, the banknotes are compressed into a bundle between the banknote compression plate, which is spring-biased toward the conveyance path at the entrance of the stacking location, and a pair of channel members that limit the entrance to the stacking location.

On the other hand, motor overload detection is performed as follows.

A timer starts at the start of the stroke of the reciprocating means,
A timer runs a length of time corresponding to the time normally required for the motor to drive the reciprocating means through one reciprocating stroke of the reciprocating means. If the load is not large, the operation of the carrier switch means ends during the timer operation. If the load is large, the operation of the carrier switch means will not end during the timer operation. The control means confirms that the operation of the carrier switch means is not completed within the timer operation time, and thereby indicates that the reciprocating means has not passed the predetermined travel distance within a certain predetermined time. do. thus.

Overload detected. Based on this indication, it is determined that the reciprocating stage has not traversed the predetermined stroke distance within the predetermined time interval;

The motor is reversely rotated to retract the reciprocating means. Therefore, it is possible to avoid a situation where the machine or the banknote bundle is damaged by forcing the motor to rotate. In this way, it is detected that the maximum amount of banknotes has been accumulated in the accumulation area by increasing the load on the motor of the reciprocating means.

The rotation of the motor M1 is transmitted to the upper pair of pulleys 5, and the lower pair of pulleys 6 are driven to rotate. The lower pulley 6 is provided at the corner of the L-shape, and the upper pulley 5 is provided at the upper end of the L-shape, and the belt 4 extends from the corner of the L-shaped conveyance path 3 over the longer straight section, and between these, the belt 4 is attached to a banknote. A driving force is applied to the target. A rotary pulse generator RPG is provided that generates an electrical pulse signal in synchronization with the rotational position of the transport motor M1, and this pulse signal is used to identify the authenticity of banknotes based on the output of the magnetic heads H, , H, Sometimes used to create bill position address data. In other words, the magnetic distribution on the surface of one banknote shows a specific pattern corresponding to each address position on the banknote, and based on this pattern, it is possible to determine whether the banknote is genuine or false for each denomination. R1, R2, R3, and R4 are driven rollers.

A reciprocating mechanism for stacking banknotes is provided on one side (the side of the conveyor belt 4) of the longer straight portion of the L-shaped conveyance path 3. This reciprocating mechanism.

A push plate 7 for pressing the banknotes sent by the conveyor belt 4 in the surface direction, and a motor M2 for pushing the push plate 7.

According to the rotation of the motor M2, the cam 8 eccentrically rotates and presses the link rods 11a and 11b, thereby causing the push plate 7 to move in parallel in the plane direction. The push plate 7 is always pressed in the direction of the cam 8 by a spring 21.
The push plate 7 reciprocates in conjunction with the eccentric movement of the cam 8.

On the other side of the straight portion of the L-shaped conveyance path 3, there is a stacking box 12 for stacking banknotes pressed by the reciprocating mechanism.
is provided. As shown in FIG. 2, the accumulation box 12 consists of two vertical channel members 1 arranged vertically side by side with a predetermined interval slightly narrower than the width of the banknotes.
3a and 13b form an entrance, and a banknote compression plate 14 having a width corresponding to the surface size of the banknote is provided in parallel to the channel members 13a and 13b and the push plate 7. Although the channel members 13a and 13b are fixed,
The banknote compression plate 14 is movable in parallel in a direction perpendicular to the plate surface, and is always pressed toward the channel members 13a, 13b by the action of appropriately placed springs 15. A part of the channel members 13a, -3b near the conveyance path 3 is cut out, and driven rollers 16 and 17 for assisting bill feeding are provided therein. These rollers 16 and 17 are always pressed toward the belt 4 by the action of springs 18 and 19, and the banknotes conveyed as the belt 4 moves are not sandwiched between the belt 4 and the banknotes, so that they are driven to rotate. do.

In the standby state, the reciprocating mechanism is in a state as shown in FIG. It is a passageway.

A lever 2o is provided at the corner of the L-shaped conveyance path 3,
One end thereof protrudes into the passage. The lever 20 is adapted to automatically move out of the passageway when pushed by banknotes traveling in the forward direction (accepting direction), but serves as a stopper for banknotes traveling in the opposite direction. A sensor s2 is provided to detect the movement of the lever 20, and is turned on when the lever 2o exits the passageway as shown by a two-dot chain line 20' while the bill is being advanced.

Turns off when you return to the passage.

When the sensor S detects that a banknote has been inserted, the transport motor M1 rotates in the forward direction to transport the inserted banknote in the forward direction along the transport path 3. In the process, magnetic head I (□, H8
Authenticity is determined based on the output of the counter, and if the bill is a counterfeit, the motor M is reversed and the bill is immediately returned.

When the rear end of the inserted banknote that is finally determined to be a genuine banknote and has been correctly fed passes the lever 20 and the switch S is switched from on to off, a K ticket signal is output to the external usage device. It is used to count the number of coins inserted. and,
After a predetermined period of time, the normal rotation of the motor M1 is stopped, and the inserted bill is stopped at a position corresponding to the push plate 7. Next, the motor M2 is rotated in the normal direction, and a stacking operation is performed to take one bill into the box 12. A carrier switch S3 is installed on the rotating shaft of motor M2.
is provided, and controls the motor M2 to rotate once during the stacking operation. In response to one rotation of the motor M2, the eccentric cam 8 rotates once, causing the push plate 7 to reciprocate once.

When the pushing plate 7 approaches the compression plate 14, the channel member 13a pushes the banknotes in the conveyance path.

13b (at this time, the banknote bends and passes through 13b)
channel members 13a and 13b and the compression plate 1, which moves the compression plate 14 in the six directions of the arrows against the force of the spring 15 while pressing the bill against the compression plate 14.
A space is created between 4.

The pressed bill enters that space. FIG. 3 shows the state in which the reciprocating mechanism has been translated by the maximum amount.

At this time, the eccentric cam 8 has made exactly one revolution. Eccentricity ■ When the cam 8 makes one remaining rotation, the push plate 7 returns in the direction of arrow A, and the compression plate 14 is pushed toward the channel members 13a, 13b by the force of the spring 15.

When both sides of the banknote come into contact with the channel members 13a, i3b, the compression plate 14 stops moving, and the member 13a.

The banknotes are compressed and held between the compression plate 13b and the compression plate 14.

The push plate 7 returns to its original position by the force of the spring 21, leaving the held bills in the box 12.

In this way, the channel members 13a, 1 in the box 12
A large number of banknotes 22 are accumulated between the banknotes 3b and the compression plate 14.

FIG. 4 is a side view of the above-mentioned banknote device, in which the spring 1 is actually
5 indicates that it is attached to both sides of the box 12. A spring 15 is hung on a cut-out 14a provided approximately at the center of both ends of the compression plate 14, so that the cut-out 14a moves along a groove 23 on the side surface of the box. In addition, if you slightly lift the top cover 24 attached to the top of the box 12 in a latch manner as indicated by 24', the shaft 25
The box 12 can be appropriately tilted as indicated by 12' using the box 12 as a fulcrum, and the accumulated banknotes inside can thus be easily collected. A safety switch S4 is provided in connection with this box 12, and the box 12 is
', the removal from the main body is detected, and during that time, driving of the motors M1 and M2 is prohibited, making it impossible to insert one bill.

Further, while the banknotes are being accumulated in the box 12 according to the rotation of the motor M2, it is preferable to prohibit additional banknotes from being inserted.
If the sensor S of the insertion slot 1 detects a banknote during the rotation of the transport motor M1, the rotation of the transport motor M1 is prohibited or the motor M1,
(reversed), making it impossible to insert banknotes.

When the banknotes in the banknote accumulation box 12 become full, it is no longer possible to take in any further banknotes, so it is better to prohibit the insertion of a single banknote.For this purpose, some kind of fullness detection means should be used. and prohibits the rotation of the transport motor M1 when the full state is detected, or the sensor Si of the insertion port 1
When the inserted banknote is detected, the motor M1 is reversed to automatically return the banknote. As the fullness detection means, it is preferable to provide a sensor at a predetermined fullness detection position within the box 12.
Alternatively, there may be a method of detecting that the accumulation property has reached the maximum by detecting that a load of more than a predetermined value is applied to the accumulation motor M2. The fact that a load of a predetermined value or more is applied to the motor M2 can be detected by detecting whether the carrier switch S remains on for a predetermined time or more. That is, since the accumulation amount has reached the limit, the compression plate 14 no longer moves in the direction of arrow A, and the motor M2
This is because the rotation stops midway. In that case, it is preferable to reverse the motor M2 and return it to the standby state as shown in FIG.

FIG. 5 shows an example of a control program for banknote stacking operation, which includes means for detecting an overload of the motor M2 (that is, detecting that the box 12 is full) using a timer as described above. First, a 3-second timer T is started (block 26), and the motor M2 is rotated in the forward direction. The flow from block 26 to block 27 is normal control, and carrier switch S is turned on and turned off within the timer period. If the switch S3 is not turned off even after the timer time has elapsed (YES in block 28), the motor M2 is stopped.

After setting timer T again, reverse motor M2 (block 29), and confirming that carrier switch S is turned off (block 30 YES), set the full detection flag.The 0m full detection flag is set. When this occurs, a predetermined fullness display is performed and the insertion of banknotes is prohibited.

〔Effect of the invention〕

As described above, according to the present invention, since the configuration is such that the accumulation of the maximum amount of banknotes in the stacking place is detected by an increase in the load on the motor of the reciprocating means, a special dedicated switch for stacking the maximum amount of banknotes is required. This is unnecessary, and this will have a negative impact on cost and configuration scale due to the need to secure space for the switch and increase the number of parts, and may also cause detection to become undetectable due to switch failure. It has the excellent effect of being able to solve the problems of Furthermore, when an increase in load is detected, the motor is rotated in the opposite direction to pull back the reciprocating means, so it is possible to avoid a situation where the motor is forced to rotate and damage the machine or the banknote bundle. play.
